Configure CMDB Health metrics aggregation preferences

Sub-metrics health scorecards are aggregated into their respective major metric,
which in return are aggregated into the overall CMDB Health report. Set metric aggregation
preferences for the major metrics, and for each of their sub-metrics, deactivate metrics
that you are not interested in reporting, and adjust weighted averages of
aggregation.

The completeness metric for example, consists of the sub-metrics required
fields and recommended fields, each contributing
a different weight to the sum. You can configure the proportional weight of required
fields and recommended fields within completeness to be 25 and 75 respectively. You
can also configure the proportional weight of completeness, compliance and
correctness within the aggregated sum of the overall CMDB health.

Note: Non-active metrics are displayed on the CMDB dashboard in faded coloring,
displaying the most recent aggregations that were calculated when the metric was
active.

In the ServiceNow base system,
the weights of the main metrics have default settings, and each sub-metric is
globally set.

Procedure

Navigate to Configuration > Health Properties.

Select Health Metrics on the right-hand side
navigator.

Expand Select Metric and select one of the main metrics
such as Completeness, or a sub-metric.

For Completeness, Compliance and
Correctness:

Field

Description

Active

Activate the metric to include it in the aggregated CMDB
health report.

Weighted Averages

Specify the weight of each sub-metric in the aggregated
health report for the metric. The sum of weighted averages
for all sub-metrics should be 100.

For a sub-metric:

Field

Description

Active

Activate the metric so it is included in the aggregated
health report for the respective metric.

Create Task

If a record fails the metric test, create a task with
details about the failure. You can then view the task on the
CI dashboard, and configure remediation for the
task.

Failure Threshold

When the threshold number of CIs that fail the health
metric test is reached, health processing stops for the
metric for this cycle.
